John McCain:

My friends, we have reached a crisis, the first probably serious crisis internationally since the end of the Cold War. This is an act of aggression.

McCain last month:

McCAIN: The fact is we had four years of failed policy. We were losing. We were losing the war in Iraq. The consequences of failure and defeat of the United States of America in the first major conflict since 9/11 would have had devastating impacts throughout the region and the world.

Of course Afghanistan doesn’t even merit mention from McCain. More at Think Progress.
